Light flickering and fluctuation

Hi guys, I’m facing a lighting issue when exporting a video. The light appears to flicker or move like water ripples. What could be the reason for this? I tried using different types of IES lights but I’m still facing the same problem.

Hi @zayod.151

I apologize for the inconvenience. Have you tried disabling Super Resolution or FPS Booster? Please try it.

If the issue persists, we may need to collect your D5 Render File so we can test it on our end. Please let know if my suggestion did not do anything.

Hey, try turning off cast shadow option under light settings. It worked for me :slightly_smiling_face:

Hello friends,
Thank you for your support. I have tried all the solutions you suggested, but unfortunately none of them worked.

Hi @zayod.151

I have tested your file, and there are no unnecessary light swaying on my end. Have you perhaps tried updating your GPU Drivers or perhaps reinstall D5 Render?

I modified the IES settings, set it as the default, and adjusted the light angle settings — and the issue was resolved.

Hi @zayod.151

Thanks for your update, we really appreciate it.
